I'm having trouble compiling a source file consisting of the following single line: #include <boost/multi_index/ordered_index.hpp> Using gcc 3.3.5, I get the following error: In file included from t.cpp:1: .../boost_1_33_0/boost/multi_index/ordered_index.hpp: In member function `void boost::multi_index::detail::ordered_index<KeyFromValue, Compare, SuperMeta, TagList, Category>::rearranger(boost::multi_index::detail::ordered_index_node<typename SuperMeta::type::node_type>*, boost::multi_index::detail::ordered_index_node<typename SuperMeta::type::node_type>*)': .../boost_1_33_0/boost/multi_index/ordered_index.hpp:1092: error: no class template named `archive_exception' in `boost::archive' Needless to say this used to work with Boost 1.32 :) Regards, Eelis
